Traveling Wave Antenna - SlideShare
A travelling-wave fed parallel plate slot array antenna The paper demonstrates a travelling-wave parallel plate slot array antenna capable of generating inclined linear polarisation with good cross-polarisation characteristics at 60 GHz, taking advantage of the rotated series slot elements, in order to reduce the interference from other systems. First, the attention is focused on the design philosophy of the travelling-wave fed parallel plate slot
